MACHINE FOR WASHING BOTTLES AND THE LlKE.

Specification of Letters Patent.

Patented May 21, 1907.

Application filed February 13, 1905. Serial No. 245,610.

the following is a specification.

This invention relates to machines for washing bottles, eroeks, gallipots, plates and other articles of a like nature; .my object being to thoroughly cleanse such vessels, both internally and externally, and to treat several simultaneously the operation being of a continuous character.

In the accompanying drawings, which illustrate a washing machine embodying my improvements, Figure l is a vertical section of the machine and Fig. 2 a face view of the radial arms. Figs. 3 and 4 are respectively a vertical section of the socket for the mouth of the bottle, and a face view of the water supply valve, both to an enlarged scale. Fig. 5 is a detail view of the driving mechanism, while Figs. 6 and 7 illustrate respectively in side elevation and plan the means for cleansing the exterior of the articles.

In constructing apparatus adapted for carrying out my invention, I mount, upon a main driving shaft A a hub B provided with radially arranged arms I); and on each arm is mounted a-carrier 0, adapted for the reception of the bottle or other article to be cleansed and arranged to slide on the said arms.

A disk D formed with a cam-groove d in which a pin or roller 0 projecting from each carrier 0 engages, serves to move each carrier in succession toward the axis of the ma chine and subsequently in the opposite di rection, so as to remove the bottle from an internal brush hereinafter described.

Under such circumstances the cam-groove may be formed and the cam set in such a manner as to prolong the action of the internal brush at the full depth of the bottle.

The carriers 0 are provided with socket c and an arm 0 adapted to suit the article to be cleansed, as for example the bottle 0, and to hold the same in position while it is rotated upon its axis as hereinafter described. The socket c for the mouth of the bottle is preferably constructed as shown in Fig. 3, wherein a spring-supported member 0 adapted to en gage the mouth of the bottle is free to slide in a sleeve 0 formed with projections c whereby the sleeve 0 together with the member a may be rotated, 1 i

Co-axial with each carrier is a tube E perforated at its extremity and furnished with bristles or rubbers e -for the purpose of scouring the interior of the bottle. Each tube E is secured to the spindle e of a bevel pinion e mounted in the hub B, and each bevel pinion meshes with a bevel-wheel e keyed on the main shaft A of the machine whereby the tubes E are rotated. 'Each tube is in communication with a water supply nozzle F by way of passages 6 formed axially in the bevel pinions e and passages f" in a rotary 'valvef freely mounted on the shaft A. The

one extremity of the spindle e engages in the rotary valve while the opposite end is supported in the hub B which latter during its rotation rotates the v'alvef The nozzle F is furnished with ports f for water and a portf for air and as the valvef rotates each passage f is brought alternately into communication with these ports. Air is supplied under pressure by means of a pumpf driven from a diskf mounted on. the main shaft A, while the water is supplied in the ordinary manner. The position of the ports in the nozzle F are so arranged that, as the valvef is rotated, water is first admitted to the tube E then air to discharge the water after cleans ing then a further supply of water to rinse out the article.

For the purpose of cleaning the exterior of the bottle I key to the main shaft A a toothed wheel gin mesh with another wheel g mounted on a bracket h. From this bracket is suspended by means of links g a pair of brushes G which are oscillated by means of a rod g connecting the wheel g with the suspending link 9 The bristles of the brushes project into the path of the bottles and bear against the latter, which are rotated while in contact with the brushes. The rotation of the bottle is effected by a bevel pinion g sleeved on the spindle e of the bevel wheel 6 and in mesh with a stationary bevel wheel 9 a projection 9 being formed on the bevel pinion g with which the projections c on the carrier C engage when the latter is at about its nearest position toward the axis of the machine.

The cleaning apparatus is mounted upon brackets 7t 7L attached to one of the side Walls of a tank H containing water into which the bottles dip in the course of their journey round the axis of the machine.

IIO

The main-shaft A is providedwith fast and i speed of the main-shaft.

The operation of washing a bottle, for ex ample, is as follows :As each bottle-carrier C arrives in its highest position, a bottle is inserted therein; and, as the rotation of the entire series of radially arranged bottle-carriers continues, the bottle gradually dips into the tank, is rotated on its own axis by the bevel gearing g g and is at the same time moved longitudinally upon the internal brush or scarifier, through which the internal washing water is introduced. Upon the bottle reaching its lowest position, the internal brush becomes inserted to the depth of the bottle and While in this position the action of the brush is prolonged on the bottom of thebottle, the cam-groove being so formed for this purpose; but as the movement proceeds the bottle is gradually withdrawn from the brush. Simultaneously with the operation of cleaning the interior of the bottle, the exterior thereof is subjected to the scarifying effect of the brushes G, the bottles being meanwhile bathed both externally and internally.

Instead of furnishing the internal brush with bristles in the ordinary manner, it may be furnished with two or more strips of rubber as shown, and as such a brush is rapidly rotated the centrifugal force opens out the strips the latter being thereby brought into intimate and rubbing contact with the internal surface of the bottle.

What I claim as my invention and desire to secure by Letters Patent is 1. A bottle-washing machine comprising a rotatable hub furnished with radial arms a bottle-carrier reciprocably mounted on each of said arms, a cam supporting said bottlecarriers and reciprocating them on the radial arms, rotatable water-spray nozzles co-axial with said bottle-carriers and furnished with rubbers over which the bottles are passed, means for rotating said hub and radial arms, and means for rotating said Water-spray nozzles.

2. A bottle-washing machine comprising a rotatinghub furnished with radial arms, a bottle-carrier reciprocably mounted on each of said arms, a cam supporting said carriers and reciprocating them on the radial arms, a socket rotatably mounted in each bottle-carrier and holding the mouth of the bottle, means for rotating said socket, a brush suspended in the path of the bottle, and means for oscillating the brush against the exterior of the bottle.

3. In a machine for washing bottles, the

combination, with a tank and a rotating Wa ter-spray nozzle furnished with rubbers, of a bottle-carrier mounted to slide to and fro in the axial direction of the bottle and provided with a spring-supported socket for holding the mouth of the bottle, and means for imparting a rotative movement to said bottle.

4. In a machine for Washing bottles, the combination, with a rotatable hub furnished with radial arms and a bottle-carrier reciprocably mounted on each of said arms, of a rotary valve, water-spraynozzles mounted on said valve co-axial with said bottle-carriers, and a waterandair supply nozzle; the said valve, while rotating, admitting water and air alternately to each of said water-spraynozzles successively from said water-and-air supply nozzle.

5. In a machine for Washing bottles and other articles of a like nature, the combination, with a series of reciprocably-mounted bottle carriers, and water spray nozzles mounted co-axially therewith, of an air-pump for supplying air under pressure to the bottles, substantially as and for the purpose set forth.

In testimony whereof I have signed my name to this specification in the presence of two subscribing Witnesses.
